Chapter 4

• In June 2006, PPU version B.08.00 was delivered on the HP-UX 11i v1 Application

Release (AR) media and provided the following features:

— Support for HP Integrity Virtual Machines Environment.

— PPU now requires NParProvider version B.12.01.06.01 or greater.

— The Utility Pricing program changed terminology to be consistent with the new

HP definitions of “processor,” “CPU” and “core.” The two metrics previously

known as “Percent CPU” and “Active CPU” are now called “Percent Core” and

“Active Core.”

• In December 2006, PPU version B.08.00.01 is delivered on the HP-UX 11i v1

Operating Environments and provides the following features:

— Defect fix for error message reported when cells are powered down.

Impact

PPU Version B.11.11.08.00.01 supersedes version B.11.11.08.00 on HP-UX 11i v1.

The two metrics for measuring pricing and utilization are now called Percent Core and

Active Core (previously known as Percent CPU or Processor Percent, and Active CPU or

Number Active Processors). The billing amounts vary as your core usage increases or

decreases. This is different than traditional financing approaches that are based on

fixed-payment amounts for a specified period. PPU can be run in an HP Integrity Virtual

Machines environment (HPVM). In this case, the usage information for billing purposes

is still the overall usage for the host. However, you can examine the usage report at the

portal to see a detailed breakdown of the usage for each Virtual Machine (also called a

“guest”). In an HPVM environment, PPU needs to be installed and configured only on

the host, not on the guest Virtual Machines. (PPU commands are therefore only executed

on the host.)

Compatibility

While the utilization metric names have changed, as well as other terminology, the

methods of measuring resource utilization have not changed. There are no known

compatibility issues.

Performance

There are no known performance issues.
